Installing Burris FFII on barrel

Hi everyone,

I am in need of info about how many Inch/Pounds of torque that can be applied to UTG Universal Shotgun Single-Rail Barrel Mount (Picatinny rail) to install Fast Fire II red dot unit right on the barrel itself, just in front of fore-end, without distorting/squizing barrel. The gun is single shot, brake open 12-ga made in Rus. Federation by IZH (Baikal) known as MP-18.

The UTG barrel mount is aluminum and held arround barrel by 4-ea steel machine screws size: 8x36.
Length of mount = 1.575”, inside of mount has 4-equaly spaced flat surfaces that contact barrel each flat is 0.130” thick.

The barrel (at point where mount will be attached) is 0.072” thick on each side.

No spacer of any kind between mount and barrel.

Steel shot to be used mostly #6, #4, #3 and #2, very seldom “BB”. Load 1-oz., 1.320 to 1.480 fps., to avoid exessive recoil.

Any and all info on this matter will be greatly appreciated.

Why not just DnT the barrel over the chamber for the Marlin 336 mount and be done with it? Should be thick enough to handle it and the recoil forces are distributed a bit differently further back and it'll sit a lot lower on the gun so you won't have to take your cheek up off the stock every time you shoot and smack yourself in the cheek.

A mount for an H&R turkey gun or handy rifle would probably fit perfectly.

True, but seing as the FF II is so small, the Marlin 336 mount on the round barrel wold be perfect for shotguns wih no Vent Rib, plus it will keep the site MUCH lower on the gun, making site aquisition much easier and faster. The other plus is that you'd omly be drilling 2 holes, not 3 or 4.

Doesn't the 336 have a fairly flat topped receiver though?

It should be rounded enough to fit.
